Your Breville Precision Brewer has been designed to make coffee of the highest quality, just the way you like it, no matter what style of coffee you enjoy.
Fast: Brew up to 12 cups (60oz) as fast as the brewer can deliver the water in the tank.
Gold: This mode has been certified by the SCA (Specialty Coffee Association) to meet their rigorous technical requirements using the Cone Filter Basket and water volumes of 1.0L & 1.2L together with a brew ratio of 55g of coffee to 1.0L of water.
Strong: Brew settings are automatically adjusted so you get a stronger cup of coffee. Tip: for strong coffee, increase the amount of ground coffee you normally use.
Over Ice: Brew up to 4 cups (20oz) of stronger coffee that tastes great when poured over ice and garnished any way you like.
MyBrew: Brew up to 12 cups (60oz) having total control over all the variables, brew water temperature, bloom time, water delivery speed, so you get coffee just the way you like it.
Cold Brew: Brew up to 20oz of Cold Brew coffee with the flexibility to adjust steeping time between 0-24 hours and have the coffee automatically delivered into your favorite vessel.
The SCA recognizes home brewers that meet their longstanding rigorous technical requirements. These requirements are based on decades of industry knowledge and research by the Coffee Brewing Center. All SCA Certified Home Brewers have met these requirements, which are based generally on proper water temperature, brewing time, and ability to brew within the SCA Golden Cup recommendations.
If a brewer passes all of the tests in the certification procedure, as conducted by the SCA, that brewer will be eligible to be recognized as an examplary home brewer and join the short list of SCA Certified Home Brewers.
The Breville Precision Brewer has met these SCA requirements when using the "Gold" setting and the Cone Filter basket.

Unpack all parts and accessories before removing and safely discarding all packaging material and promotional labels. Ensure the power cord is unplugged from the power outlet.
Wipe the exterior stainless steel housing with a soft, damp cloth. Wash the lid, brew basket, cone filter insert, mesh basket filter, and carafe in warm, soapy water and a soft cloth. Do not use abrasive cleansers, pads or cloths which can scratch the surface. Rinse and dry thoroughly. Press carafe drip stop ensuring it can freely move up and down.
When first turned on, the machine will show 'HArd' on LCD, asking you water hardness level. Press SELECT dial once. Dip the water hardness test strip into the filled water tank for 1 second, remove and wait for 1 minute to reveal the result. Rotate SELECT dial and press the dial to select the level accordingly. To reset water hardness, please refer to FACTORY RESET (page 18).

3. After flushing, empty the basket and carafe.
NOTE We recommend to flush once more in Fast mode.
Ensure the brew basket is clean and the drip stop seal in the bottom of the basket is clean and free of coffee particles.
1. Select the correct basket & filter for the amount of coffee you’re making. When brewing between 2 and 8 cups, we recommend you use the Cone shaped filter basket insert with paper filter (Cone paper filter is not included). When brewing more than 8 cups, use mesh basket filter or flat bottom brew basket with large paper filter.

CAUTION Filling the basket without a mesh basket filter or filter paper may cause the basket to overflow during the brewing cycle.
2. The LCD will display the basket setting - "Basket" or "Cone". To change the basket type, rotate the SELECT dial to Settings & press the dial. Rotate the SELECT dial to the basket type, press the SELECT dial to set.
3. Fill the water tank with fresh cold water up to the MAX marking on the water tank.

NOTE This machine will brew all the water in the tank. Ensure the tank does not contain an excess amount of water.
4. For the very best tasting coffee, we recommend using freshly roasted whole bean coffee and grind with a burr grinder directly before you brew. The grind should be medium/coarse, never use coffee ground for espresso as your coffee basket may overflow.
5. Grind enough coffee beans for the volume you’re making. For a full 60oz carafe, we recommend 3.5oz (99g) of coffee, approximately 12 level Breville measuring scoops. Roughly 1 scoop for every 5oz. Refer coffee/water ratio chart on page 16.
6. Insert the correct filter paper, cone or flat bottom, or mesh basket, into the brew basket, then, add your ground coffee. Insert the brew basket into the machine.
NOTE Never use both mesh basket filter and paper filter at the same time.
NOTE Coffee with superior taste & clarity will come from using a paper filter.
NOTE The mesh basket filter will allow some fine coffee grounds to brew into the coffee. This will appear as sediment in the cup or carafe. This is normal. Only use the mesh basket filter provided as others may cause the machine to overflow.
7. Lock the carafe lid and place the carafe under the drip stop outlet.

CAUTION The carafe MUST be in place before you brew with water level higher than ‘SINGLE CUP’ line. Otherwise the coffee basket will overflow.
NOTE Always ensure your carafe is clean and empty before brewing. Residual coffee will affect the taste and liquid in the carafe will cause it to overflow.
NOTE Always ensure your carafe is EMPTY before brewing to prevent overflow.
8. Rotate the SELECT dial to the desired mode. Press the START|CANCEL button. The machine will display the progress:
9. When your coffee is ready, the machine will beep 3 times. The machine will display the “Time since brewed”.

NOTE Never fill the water tank once the coffee machine has started a brewing cycle.
NOTE OVER ICE mode and COLD BREW mode will be disabled if there is more than 20oz of water in the tank.
1. Your Breville Precision Brewer will recognize when the brewer has less than 4 cups (20oz) of water & will adjust the brew settings, automatically, to make the best possible tasting coffee. Fill your cup with fresh cold water and then pour it into the water tank, ensuring the water level stays below the SINGLE CUP line.

NOTE DO NOT fill the water tank more than SINGLE CUP line or the volume of the cup used to receive the coffee. It will overflow as the machine brews until the water tank becomes empty.
2. Place your empty cup underneath the brew basket outlet.
3. We recommend using cone filter basket insert for single cups. It ensures proper contact between the brew water and the ground coffee.
4. To change the basket type, rotate the SELECT dial to Settings and press to enter the Settings mode and select "Basket Type".
5. Rotate the dial to select “Cone”, and press dial to select. “Cone” will be displayed on the LCD.
6. Insert the Cone filter basket into the brew basket. Use the alignment marks as a guide.
7. Place a cone shaped paper filter into the cone filter basket.
8. Grind the correct amount of whole bean coffee for the amount you are brewing. 1 level Breville scoop of ground coffee is suitable for 5oz (150ml) of water.
9. Select desired brewing mode, Fast, Gold, MyBrew or Strong.
10.Press START|CANCEL to begin brewing.
Allows you to automatically start brewing at preset time.
1. Set filter basket type for the amount of coffee you're brewing.
2. Select your brewing mode.

We recommend 1 level Breville scoop of coffee grounds per 5oz (150ml) cup of water. Adjust the amount according to your individual taste. The maximum capacity for pre-ground coffee is 12 level Breville scoops. Exceeding this amount may cause the coffee basket to overflow.

When coffee is roasted, CO2 is trapped inside the bean. Coffee grounds release this CO2 when hot water hits them, and this is called “blooming”. Your Brewer can automatically adjust bloom time by controlling the water flow. Blooming can have an impact on the aromas and flavors of the brewed cup. If the coffee is overly bitter shorten bloom time, and if it’s sour make it a little longer.
Pre-heat the carafe or cup for best results. A pre-heated carafe or cup will help maintain the coffee’s optimal temperature and keep coffee hotter for longer. Fill with hot water for about 30 seconds then discard the water.
Fresh, good-tasting water is essential for a perfect cup. If the water contains excessive sediment, or has an ‘off’ taste or odor, we recommend using filtered water.
NOTE If using granulated sugar as a sweetener, add while the coffee is hot to encourage the sugar to completely dissolve.
Your Brewer will produce a maximum of 20oz of Cold Brew. Due to the long duration (typically 4-14 hours) of the brewing process we recommend setting the machine up overnight so the Cold Brew will be ready in the morning.
1. Fill the tank with your desired volume of water ensuring this is below the COLD BREW line.
2. Remove the basket, and ensure both the cone insert and mesh basket filter are removed. Add a large paper filter and then coffee at 2-3 times of regular ratio (approximately 12 scoops for 20oz). Reinsert the basket into the machine.
3. Remove the lid from the carafe and re-insert – the lid must not be on the carafe during the brewing process, alternatively, use another vessel.
4. Navigate to the COLD BREW setting and press START|CANCEL. The machine will then begin brewing the water without the heating element. Once this is complete a countdown timer will display on the LCD indicating when the Cold Brew is finished. At this point the machine will automatically dispense the Cold Brew into the waiting carafe
NOTE Brew Time for Cold Brew can easily be adjusted to your preference, anywhere between 1min – 24hrs.
NOTE Do not add ice to the tank. Cold, chilled water should be added.
Always turn the coffee machine off and remove the plug from the power outlet before cleaning.
The outer housing and LCD screen can be cleaned with a soft, damp cloth. Apply cleaner to the cloth and not the LCD surface. Polish with a soft, dry cloth. Cleaning and drying with dry paper towels or abrasive cloths and cleaners may scratch the surface.
Remove the coffee basket. Discard any ground coffee and filter paper. The coffee basket and mesh basket filter can be rinsed under running water. Ensure the fine holes of the mesh basket filter are clear. For a deeper clean, wash the coffee basket and mesh basket filter in warm, soapy water with a soft bristled brush.
CAUTION The coffee basket, mesh basket or paper filter may still be very hot after brewing. Use caution and allow to cool before removing.
After each use, empty the carafe. Do not let brewed coffee stand overnight as this can cause the carafe to stain. Rinse the carafe and carafe lid under warm running water. For a deeper clean, we recommend regularly washing the carafe in warm, soapy water using a soft bristled brush. Do not use abrasive cleansers, pads or cloths which can scratch the surface. Rinse and dry thoroughly.
Simply wipe down the showerhead area periodically. However, if a more thorough clean is required, the Showerhead can be removed by unlocking the Showerhead Ring. Rotate clockwise then remove the Showerhead for cleaning. Once complete, reinstall the Showerhead.
After regular use, hard water can cause mineral build up in internal components, reducing the brewing flow, brewing temperature, power of the machine, and taste of the coffee. We recommend to descale regularly. When LCD shows “DESCALE” (flashing), descaling cycle is needed
NOTE It takes approximately 15 minutes to complete descaling cycle.
1. Empty the tank. Prepare a descale solution in accordance with manufacturer's instructions. Pour this solution into the empty water tank.
2. Place the basket and the carafe into position under the drip stop outlet (Ensure the carafe is empty and the lid is securely locked).
3. Press SELECT button for 3 seconds to start descaling cycle. LCD with show “dSL” for 1 second and then tell remaining time of descaling cycle.
4. When the descaling process is finished, the LCD screen will go back to the main menu. To completely remove residual water in the tank, invert the machine and brew with fresh water twice. Discard the water from the carafe and rinse thoroughly
NOTE We recommend to brew through again after descaling to brew out the residue descale solution.
NOTE You cannot stop the descaling process mid cycle. Force stop by unplugging the cord from the power outlet.
This is to reset the machine to the factory settings, including water hardness setting. Hold the START button, the SELECT button, and AUTO START button altogether for 3 seconds. When LCD shows “rES” (flashing), press SELECT button to start. Then next prompt asks “YES” or “no” to confirm. Rotate and press SELECT dial/ button.
